7 PETER KELLER, OF NEW YORK, N. Y., ASSIGNOR TO THE GAS GARBURETTER AND EOONOMIZING COMPANY, OF SAME PLACE.

GAS-CARBURETER.

SPECIFICATION forming part of Letters Patent No. 237,752, dated February 15, 1881.

Application filed August 17, 1880.

To all whom it may concern:

Be it known that I, PETER KELLER, a citizen of the United States, residing at New York, in the county and State of New York,

have invented new and useful Improvements in Gas-Oarbureters, of which the following is a specification.

This invention relates to that class of apparatus in which the gas circulates in tubes containing wicks which are immersed in a volatile hydrocarbon liquid; and it consists in a certain novel manner of combining with the apparatus a check'valve or regulator, in order to prevent waste, not only of the gas, but

also of the hydrocarbon vapor.

This invention is illustrated in the accompanying drawings, in which Figure 1 represents a vertical central section. Fig. 2 is a plan or top view. Fig. 3 is a horizontal see- Fig. 4 shows one of the wick-tubes in side view. Fig. 5 is a vertical central section of the check-valve.

Similar letters indicate corresponding parts.

The letter A designates the body of the apparatus; B B, the wicks; O O, the wick-tubes,

and D the check-valve.

The body A is an air-tight vessel, and is equipped with screw-nipples a b, one of which is a gas-inlet orifice and the other a gas-outlet o orifice. In the center of the vessel composing the body A is a partition, 0, whereby it is divided into two compartments, which communicate with each other by a space or opening formed by terminating the'partition above the 3 5 bottom of the vessel, and also by holes 6 formed in the upper part of the partition.

The wicks B B respectively consist of strips of cotton or other suitable material, which are suspended from cross-bars f located in the up- 40 per parts of the wick-tubes O C. These crossbars f are arranged in two rows, those of one row alternating with those of the other, so that the bars are least liable to interrupt the flow of the gas.

The wick-tubes U G are made of sheet metal or other like material, and each tube is provided with a series of lateral openings, 9. The position of the wick-tubes O 0 is in the compartments of the vessel A and beneath the gas inlet and outlet orifices, respectively, the

(No model.)

tubes extending from the top to the bottom of the vessel.

The check-valve D is located at the top of the wick-tube O, and it consists of a shell, it, having a flange, 6, whereby it is secured to the top of the vessel A, of a nipple, j, arranged within the shell, and a valve proper, It, having its seat on the nipple. The shell h of the check-valve is fitted into the wick-tube O, and the nipple 12, forming the gas-outlet, is cast on such shell.

In applying the apparatus the vessel A is supplied with a suitable hydrocarbon liquid, as through a nipple, l, and the wicks B B become immersed therein-namely, in that which enters the wick-tubes through their openings g. The gas admitted to the apparatus circulates through the wick-tube G, and, escaping therefrom through its openings g, enters the compartment containing such tube. The gas then passes into the other compartment through the holes 0, and enters the wick-tube 0, through which it circulates, whence it flows through the check-valve D and escapes. In this manner the gas is impregnated with hydrocarbon vapor, which materially increases its illuminating power, while the gas and vapor escape together through the check-valve D, which serves to regulate the pressure thereof and prevent waste. The operation of the check-valve D is well known and needs no description.

Prior to my invention a gas-regulator has been provided with a gravity-valve arranged to be raised by the flowing gas when more than one burner is employed, as in my patent of May 25, 1880; but in such apparatus no slotted tube and wick are employed, as in my present invention.

In my patent of June 3, 1879, a gas-carbureter is provided with perforated tubes of cot- 0 ton fabric stretched upon a wire coil; but no valve is employed, nor is the employment of a slotted tube inclosing a wick suggested in such connection.

Other carbureters have been provided with 5 check valves connected with flexible diaphragms; but such are not used in connection with a slotted tube inclosing a wick.

What I claim as new, and desire to secure by Letters Patent, is roo 1. The combination, with the wiok-tubesG O, of the check valve or regulator D, located at the upper end of one of such tubes, substantially as and for the purpose described.

2. In a gas-carbureter, the combination, with an air-tight vessel, A, constructed with a depending partition, dividing it into two compartments, having respectively the inlet and outlet connections or nipples to b, the wicktubes G 0, provided with the suspended wicks, and extending from the upper to the lower ends of the compartments of the vessel, and having lateral openings 9 g, and the check-
